查询词典 shale

Also, America's shale-gas revolution, coinciding with recession, has left the market oversupplied.

同时，美国革命性的页岩气技术恰逢经济大衰退，导致市场供应过剩。

Are now conducting the research and development of in-situ or surface retorting of oil shale for producing shele oil.

美国则有29家公司正在进行油页岩地下和地上干馏炼油的开发研究。

The original commentary is about typical technologies for oil shale retorting.

介绍了当今世界典型的油页岩干馏技术。

In this dissertation, an experimental and modeling study on single oil shale lumps with sizes of 10-60mm in diameter was performed to simulate the operation steps during industrial retorting of oil shales, which is found to be the original attempt in China.

在油页岩的低温干馏过程中，通常是利用块状页岩作为装置进料，因此，对块状页岩热解特性的研究，将为加工装置的操作、设计及改进提供更为可靠的理。。。

The convection heats that is apart from to 13 meters between the well heats the oil shale retorting mine process, heat the temperature as 600°C. Adopting single crack heating to need 4 years can make the whole hot solution district attain 500°C above, the adoption double crack heating need a year and can make whole hot solution the district attain 600°Cs or so.

3在井间距为13米的对流加热油页岩干馏开采过程中，加热温度为600℃，采用单裂缝加热需要4年就可使整个热解区域达到500℃以上，采用双裂缝加热需要1年就可使整个热解区域达到600℃左右。

Exchange the heating well and the oil extraction well that the much more above-mentioned well electricity heat the oil shale retorting mine, continue to heat to mine. 5 after years, the temperature that is apart from to heat the or so place of 6 meters of well is also only is 500°C, but heat whole temperatures of the nearby rock strata of wells all very high, cause the calories follow the peripheral rock strata in great quantities lost.

2将上述多井电加热油页岩干馏开采的加热井与采油井交换位置，继续加热开采。5年后，距加热井6米左右的地方温度也仅为500℃，而待采油页岩层与邻近地层的接触面处整体温度很高，说明在整个开采过程中油页岩层向邻近地层散失了大量的热。

The oil yield of six types of Huadian oil shales were measured on a Fischer assay retort,and the factors which effected the results of Fischer assay of oil shale were investigated,such as heating rate,particle size,final retorting temperature and retorting persistent time.

结果表明，页岩油的产率随着挥发分含量的增大而增加，在一定范围内提高升温速率，页岩油产率增大，但升温速率过快，反而使页岩油产率降低；终温在500℃~510℃，持温时间20 min的条件下，产油率最高，继续增加干馏终温和持续时间对产油率影响不大；同时适宜的粒度可以适当提高页岩油的产率。

Shale is intercalated with storm-generated sandstone and grain- stone beds that become more common and thicken upward, indicating progressive shallowing.

页岩夹于风暴形成的砂岩中和颗粒灰岩层中，向上变得更多见并加厚，表明水逐渐变浅。

Manganese mine basically originates in basin center inferior inside the small photograph of manganese mine of carbonic acid of black shale clip of the photograph.

锰矿主要产于盆地中心亚相的黑色页岩夹碳酸锰矿微相内。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
